MAST: a mass spectrometer telescope for studies of the isotopic composition of solar, anomalous, and galactic cosmic ray nuclei
نویسندگان
چکیده
The Mass Spectrometer Telescope (MAST) on SAMPEX is designed to provide high resolution measurements of the isotopic composition of energetic nuclei from He to Ni (Z = 2 to 28) over the energy range from -10 to several hundred MeV/nuc. During large solar flares MAST will measure the isotopic abundances of solar energetic particles to determine directly the composition of the solar corona, while during solar quiet times MAST will study the isotopic composition of galactic cosmic rays. In addition, MAST will measure the isotopic composition of both interplanetary and trapped fluxes of anomalous cosmic rays, believed to be a sample of the nearby interstellar medium.

The Isotopic Composition of the Anomalous Low-energy Cosmic Rays
We present new observations of the isotopic composition of low-energy He, C, N, 0, and Ne nuclei. The observations cover the energy interval from ,...., 5 to 30 MeV per nucleon, the energy range where the "anomalous cosmic ray" fluxes of He, N, 0, and Ne have been observed. We compare the isotopic composition of the anomalous cosmic rays with that of higher-energy galactic cosmic rays in an eff...

We compare observations of the modulated intensities and spectra of galactic cosmic ray nuclei and anomalous heliumabove 30MeV/nmeasured by theCOsmic andSolar Particle INvestigations (COSPIN) High Energy Telescope (HET) on Ulysses with similar observations from the IMP-8 earthorbiting satellite between September 1994 and August 1995. During this interval Ulysses made a rapid scan of solar latit...
متن کاملThe Isotopic Composition of Cosmic Ray
We report new high resolution measurements of the elemental and isotopic composition of galactic cosmic ray B, C, N, and 0 nuclei with ~ 30 to ~ 130 MeV nucleon-•. These observations place limits on the isotopic composition of the cosmic ray source and restrict possible models of cosmic ray origin and propagation. In particular, we find that N is significantly depleted in the cosmic ray source ...

One of the main factors for satellite design is simulating of total ionizing dose due to space ionizing rays in devices used in space. By measurement of induced dose based on available data in different altitudes, expenses of designing, satellite weight and amount of needed fuel will be reduced. Optimum design of satellite for protecting satellite against ionizing radiation has considerable eff...

The Alpha Magnetic Spectrometer (AMS), whose final version AMS-02 is to be installed on the International Space Station (ISS) for at least 3 years, is a detector designed to measure charged cosmic ray spectra with energies up to the TeV region and with high energy photon detection capability up to a few hundred GeV, using state-of-the-art particle identification techniques. Following the succes...
